Anterior Disc Protrusion
An anterior disc protrusion occurs when the inner part of the disc (the nucleus pulposus) bulges into the front part of the outer ring (the annulus fibrosus).
This makes it the exact opposite of the posterior disc protrusion, where the disc wedges itself backwards.
Anterior protrusions are not as common as posterior bulges and are usually not as serious, which is why they often remain undiagnosed. The typical location of an anterior disc protrusion is the lower back at L5-S1 level.
Although not as painful as most herniated discs, it is crucial to treat this disc condition as soon as you find out about it. Read this free back pain guide and find out what you can do.
